This project provides a simple web-based tool to check the hosting information of a given domain. It utilizes a combination of HTML, CSS, JavaScript (for the frontend and user interaction) and PHP (for the backend to resolve the domain and fetch IP information). It uses the ip-api.com API to retrieve geolocation and ISP/organization data.

• Domain Input: Users can enter a domain name (e.g., example.com).
• Hosting Information: Displays the following information about the entered domain:
  • IP Address
  • Location (City, Region, Country)
  • Hosting Provider (ISP)
  • Organization
• Error Handling: Provides user-friendly error messages for invalid domains, failed resolution, and API errors.
• Loading Indicator: Shows a loading spinner while fetching information.
• Responsive Design: Adapts to different screen sizes (desktop, tablet, mobile).
• Dark Mode Support: Respects the user's system preference for dark mode.
• Clean UI: Uses a modern, minimalistic design for ease of use.

• HTML: Structure of the web page.
• CSS: Styling and layout, including responsiveness and dark mode.
• JavaScript:
  • Handles user input (domain entry, button clicks, Enter key press).
  • Makes asynchronous requests (using fetch) to the PHP backend.
  • Updates the UI with the results or error messages.
  • Manages the display of loading indicators, results, and error sections.
• PHP:
  • Receives the domain name from the JavaScript frontend.
  • Validates the domain name using regular expressions (preg_match).
  • Resolves the domain to an IP address using gethostbyname().
  • Fetches geolocation and ISP/organization details using ip-api.com.
  • Returns the results as a JSON object to the frontend.
  • Includes error handling (try-catch block) for potential exceptions.

1. Clone the repository:

   git clone https://github.com/DreamyMonk/Hosting-Checker
   cd <repository_directory>

2. Web Server: You need a web server with PHP support (e.g., Apache, Nginx, XAMPP, MAMP, WAMP). Place the files (index.html and check_domain.php) in the web server's document root (e.g., htdocs for XAMPP, /var/www/html for many Linux setups). Make sure the PHP file has execute permissions.

3. Access the Tool: Open your web browser and navigate to the URL where you placed the files. For example, if you're using XAMPP and placed the files in htdocs, you would typically access it via http://localhost/ (or whatever directory you put the project files in).

1. Enter a Domain: Type the domain name you want to check into the input field (e.g., google.com, example.org). Do not include http:// or https://.
2. Click "Check": Press the "Check" button or press the Enter key.
3. View Results: The tool will display the IP address, location, hosting provider, and organization of the domain. If there's an error (e.g., invalid domain, unable to resolve), an error message will be shown.

This project uses the ip-api.com API. It's a free API, but be aware of their usage limits (see their documentation). If you exceed the limits, you might get rate-limited or receive incorrect data. For production use, consider:

• Caching: Implement caching of results to reduce API calls (e.g., using a database or a simple file-based cache).
• API Key: While not required for basic usage, ip-api.com may offer API keys for higher usage limits or more features. Check their documentation.
• Alternative APIs: If you need more robust features, higher rate limits, or different data, consider alternative IP geolocation APIs (e.g., MaxMind GeoIP, IP2Location). You would need to modify the PHP code to use a different API.
